Title:
AIR DISCHARGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/198573
Kind Code:
A1
Abstract:
An air discharge device (1) equipped with a duct portion (14) forming a flow path (18) enabling the passage of an operating airstream discharged toward a discharge recipient (2), and a hole formation portion (12) forming a discharge hole (10) serving as a discharge opening for the operating airstream on the airflow downstream side of the duct portion. The hole formation portion has a swirl generation structure (20) for generating an auxiliary swirl for which the swirl characteristics, including the swirl rotation direction and the swirl axis direction, differ from a lateral swirl generated on the downstream side of the opening of the discharge hole by the operating airstream. The swirl generation structure is formed in the hole formation portion such that the auxiliary swirl collides with the lateral swirl while having a swirl characteristic, that is, the swirl rotation direction and/or the swirl axis direction, that is different from that of the lateral swirl.
